Update: Doctor prescribed me Metformin to assist with weight loss. Thoughts/advice?

Ok so, I decided to give it a go and I definitely regret the shit out of that decision. I was prescribed 1000mg 2x daily and I'm pretty sure that was way too much. I started it on Tuesday, and I felt okay. I was feeling a bit lethargic and headachy, but then yesterday, I started to experience intense stomach cramping, nausea, diarrhea and vomiting. I did a little research and learned that some of these symptoms are of the norm, but once I started puking, I freaked out. My doctor isn't in on Fridays, so I plan to call him on Monday to see what's going on, but until I speak to him, I'm going to hold off on taking the pills. Is this normal though? I was symptomatic of something called lactic acidosis which is a side effect of too high a metformin dosage. Since some of you are doctors, or may have experience with this sort of thing, what do you think happened and why?
